iSmithers Rapra Publishing has announced the release of Interaction of Polymers with Polluted Atmospheres, written by Gennady Zaikov, an outstanding scientist with expertise in wide areas of chemistry who has made valuable contributions to the theory and practice of polymers.
Nitrogen oxides are common by-products of fossil fuel combustion and are one of the most significant types of air pollution. They can have considerable impact of the life of polymers in the environment and can be responsible for failure of polymer products, so it is important to know how these effects will manifest.
Most of the earlier studies have involved the determination of changes in the average molecular weight and mechanical properties, as well as changes in chemical structure using infrared spectroscopy. However, these characteristics provide no direct information on the mechanism of intermediate stages of the complicated processes of polymer degradation under the action of these aggressive gases.
In this book, novel results obtained by physicochemical methods, especially electron spin resonance spectroscopy, are considered for various polymers. The influence of different functional groups on the mechanism of interaction of nitrogen oxides with polymers are discussed. The features of ion-radical initiation of conversions of polymers by dimers of nitrogen dioxide are also considered. Various other techniques for studying these interactions are also discussed.
This handbook will be of interest to all those who produce polymer products that are likely to spend their life in an outdoors environment. It will also be useful to the manufacturers of raw materials used in these products. Technicians who are involved in material testing will also find a wealth of information about testing for the effects of ozone on polymers.
